Xiaomi Mix 4
- Incredibly fast 120W wired charging
- Bezel-less design with under-display camera
- Sleek and modern aesthetic
- Potentially superior camera image processing
- Under-display camera may compromise display quality
- Lacks gaming-specific features
- No reverse wireless charging
Asus ROG Phone 5s
- Superior thermal management for sustained gaming
- Gaming-centric features like AirTriggers
- Likely higher refresh rate display
- Potentially larger battery capacity
- Slower 65W charging
- Less refined design compared to the Mix 4
- Camera may be less emphasized
Display Comparison
Both devices feature a 6.67-inch AMOLED display, but their approaches differ. While specific refresh rates aren't provided, the ROG Phone 5s is explicitly geared towards gaming, suggesting a higher refresh rate (likely 144Hz) for smoother visuals. The Mix 4's under-display camera offers a truly bezel-less experience, a design advantage. However, this technology can sometimes impact display quality; the ROG Phone 5s' traditional notch or punch-hole design likely results in more consistent brightness and color accuracy. The absence of LTPO information for either device means we can't assess dynamic refresh rate capabilities for power saving.
Camera Comparison
Without detailed sensor information, a direct camera comparison is limited. However, Xiaomi typically emphasizes camera capabilities in its flagship devices. The Mix 4 likely features a more versatile camera system with a focus on image processing and computational photography. The ROG Phone 5s, while capable, prioritizes other features, suggesting a less emphasized camera experience. The absence of information regarding OIS (Optical Image Stabilization) on either device makes it difficult to assess low-light performance and video stabilization capabilities.
Performance
Both phones are powered by the Qualcomm SM8350 Snapdragon 888+ 5G (5 nm) with an identical CPU configuration – a Cortex-X1 prime core, three A78 performance cores, and four A55 efficiency cores. This means raw processing power will be nearly identical. The ROG Phone 5s, however, benefits from a more robust cooling system designed to sustain peak performance for longer durations during demanding gaming sessions. While both likely utilize LPDDR5 RAM, the ROG Phone 5s’ thermal management is the key differentiator, preventing the Snapdragon 888+ from throttling as quickly under sustained load.
Battery Life
The Xiaomi Mix 4 boasts a significant charging advantage with its 120W wired charging, capable of a full charge in just 15 minutes. This is substantially faster than the ROG Phone 5s’ 65W charging, which takes over 50 minutes for a full charge. While the ROG Phone 5s offers 10W reverse wired charging, the Mix 4 lacks this feature. The actual battery capacity isn't specified, but the Mix 4's faster charging mitigates the impact of a potentially smaller battery, allowing for quick top-ups throughout the day. The ROG Phone 5s likely has a larger battery to support extended gaming sessions.
Buying Guide
Buy the Xiaomi Mix 4 if you need a sleek, modern design, the fastest charging speeds available (120W wired, 50W wireless), and a more conventional smartphone experience. Buy the Asus ROG Phone 5s if you prioritize uncompromising gaming performance, extended gaming sessions without throttling, and features like AirTriggers and a high refresh rate display optimized for gaming.
